Abstract
Abstract A new crystalline aluminosilicate zeolite product is provided having a structure intermediate that of ZSM-5 and ZSM-11, having a characterizing X-ray diffraction pattern and having a unit cell parameter of at least about 40 Angstroms. There is also provided a method for synthesizing the new zeolite and a process for using the same as a catalyst in effecting conversion of organic compounds.
